This invention relates to suspended highspeed cars of the kind in whichthe passenger seats are arranged along the side walls of the car in sucha manner that the passengers sit with their backs tothese walls, whereasbetween the two rows of seats a gangway is left in which passengers canstand. The present invention relates to means for heat ing andventilating cars of this type, but in cont-radistinction to letting thefresh air rise fl-our the bottom to the top only between the rows '01seats, I have provided means for in troducing fresh air also between thebacks of the passengers and the side walls of the car in order tocounteract the strong cooling of the air withinthe car by the sideWalls; and, besides, means are provided for discharging the bad air fromabove the heads of the sitting passengers, as well as from above theheads 26 of the standing ones. The means for this latter purpose consistin two vertical longitudinal screenssuspended from those portions of theceiling of the car which are located just over the heads of thepassengers so as to separate the spaces above the heads of the sittingpersons from the space above the heads oi the standing ones. Saidscreens consist oi an opaque material, that is to say, they areimpermeable to light,- and the standing persons 30 cannot therefore lookthrough them. There are windows in the side-walls over the heads of thesittingpersons and the said screens are located between the windows ofthe two side walls of the cars. Preventing the standing personsfroinlooking through said windows is a precautionary means, in that thevery qiiickly running carsassurne in curves correspondingly obliquepositions, in consequence whereof the outer objects seem to be more orless oblique which will give rise to uneasiness, anxiety and nausea ift-hestanding persons can lookout of. the car. This is-by far less thecase with the sitting persons because they look in the direction to thesky through the windows over the oppositely seated passengers.- Moreoverthe sitting persons can look only through a comparatively small portionof the opposite windows because the screens are in the direction ofsight.

50. The invention is illustrated diagrammati- SUSPENDED HIGH-SPEEDRAILWAY CARS why and by way of example on the accomp anying drawing onwhich is shown a vertical transverse section through a suspendedhighspeed railway car designed according to the invention. ()n therighthand side of the car is shown a standing person intending to sitdown but having not yet begun to do so, and the same person is shownsitting on the bench or the like, and there are intermediaterepresentations showing again the same person in various positions asoccurring when sitting down. 2 denotes the vertical longitudinal screensmentioned in the preceding part of this specification, and 1 are theusual holding rods which are arranged as low as possible, preferablybelow the lower edges of the screens, as shown in the lelthand part ofthe figure. The rod 1 is located between the horizontal top planes of asitting person of normal size and of a standing person of normal size,and its position with respect to the sitting persons is such that onedoes not contact with it when sitting down and when rising.

The. screens 2 may be rendered non-tran parent by advertisements, alsoby diapositives or the like used at the same time for decoratingpurposes. It might seem possible to omit the screens and make use ofopaque windows, but I know from experience that this will makethepassengers uneasy and oppress them.

The wall of the ca" is, oi course, during the cold season considerablycooled by the outer air especially during running; this is even moretrue of the windows Zitrom which cin'rents of cold air iiow down ontothe necks and the napes of the passeng s, as indicated on therirghth'and side of the li urc. In order to do away with thisdisagrea-able and hurt fuldrawback, a screen (letthand side of thefigure) is provided on the top of the back of the bench or the like,this screen, which is a protective screen. extending upwardly to theproximity of the windows 3 so that the air cooled by the same is keptof? the necks and the napes of the passengers. In fact,- however, thecold air does not pass away down: through the space between the screenand the back of the bench on the one side and the inner wall of the caron the other side down to the bottom of the car, but provision is madethat a current of heated air passes upwards through the space betweensaid inner wall and the opposite parts, as more fully dealt withhereinafter. The upper edge of the protective screen l may bear tubularlamps l1.

Below the floor of the passenger room is a space a, and above theceiling of said room a space 5, and provision is made that the pres surein the space a is always greater than that in the space Z), so thatthere arise air currents, as indicated by the arrows. The outer airenters into the space a through bottom apertures 5 which are providedwith regulating means, and the bad air leaves the car through apertures7 located in the top of the car shell at the spaces 6. The air flowingfrom the space a into the interior ofthe car is divided by verticalsheet-metal walls 8 (lefthand side of the figure) into two currents, theonewfiowing into the passenger room, the other flowing along the innersides of the car shell upwardly to the windows 1 and further upwardsthrough apertures 10 into the space 5. The air present in the passengerroom escapes through apertures 9 also into the space 6, whichcommunicates with the outer air through the apertures 7. The bent-oillower portion of the sheet-metal I walls 8 may be hinged tothe upperpart, that is to say, it may be movable and adjust able, and means maybe provided for afiixingit in its adjusted position. 6 denotes heatmgbodies arranged in the space a.
